romney told a fellow bain executive, he was planning to give nearly half of his salary to the church. in an earlier interview, i was curious about the fact he doesn't drink caffeine. >> the church says no coffee or tea, it doesn't literally say caffeine. >> reporter: it doesn't? >> yeah, i try to avoid caffeine drinks, but so, if there's a caffeine free diet coke, i'll take it. but regular, i pass it up. >> reporter: and i heard that every other day, he weighs himself, to take off any pound the campaign has put on. >> that's good. if i found out i gained a couple of pounds, okay, just don't eat as much. >> oh, i hate him. >> reporter: never, ever entered my mind. >> you know, i -- i pretty much eat what i want to eat but if i notice i gained a few pounds, it's like, oh, got to slow down a bit. and, you know, otherwise, you could get as large as a house, so -- you got to watch it.
